    Bottle

    Cyanoacrylate adhesives dry more quickly than epoxy adhesives. They’re also known as super glue. Use them to secure coils of wire. To create adhesion, they require an accelerator (included with some adhesives).

    In just 20 seconds under a UV light, these urethane compounds form into a strong protective layer on electrical components. They withstand a wide range of temperatures and are good electrical insulators. They also stop chemicals, moisture, and dust from damaging your device. With excellent flexibility, they protect against vibration and impact. Since they also work as an adhesive, you can use them to bond and insulate components such as electrical connectors and thermal switches. No mixing required.

    Cartridge

    For quick repairs, these epoxies begin to harden in six minutes or less. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.
    These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    These coatings protect circuit boards and other electronics from moisture, dust, and static. They’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely. Apply these coatings without needing a potting box or other container. You can remove them if necessary.
    Urethane Rubber—Urethane rubber coatings are the best choice for harsh environments. They have the best chemical resistance in our offering, and they’re extra hard for the best resistance to scrapes. Plus, they won’t crack in low temperatures. However, they aren’t as flexible as silicone coatings, so they’re worse at handling vibration. They’re also harder to apply than acrylic coatings because they’re thicker.
    Bottle—Coatings in a bottle come with a brush for touch-ups.
    Ultraviolet—Coatings with ultraviolet visibility show up under a black light, so you can easily check if you’ve applied them evenly.
    IPC-CC-830—Coatings that meet IPC-CC-830 are certified for use on circuit boards.
    UL 94 V-0—Coatings that meet UL 94 V-0 have passed a test for flame retardance.
    Cannot Be Sold To—Coatings that cannot be sold to the listed areas are restricted due to VOCs (volatile organic compounds) regulations.

    Urethane Potting Compounds

    Encase electronic assemblies in a layer of urethane for protection from dust, moisture, chemicals, mechanical shock, and vibration. Urethanes withstand a wide range of temperatures and are the best choice for cold-temperature applications. They have excellent flexibility, good chemical and moisture resistance, and provide good electrical insulation.

    Hide proprietary information on electrical components while also protecting them from moisture, dust, and static. All it takes is a single thin layer of these black coatings. They’re often used to protect custom parts while prototyping. Place them under a UV curing lamp to fully harden them in just 5 seconds. Made of urethane rubber, they resist chemicals and scratches and won’t crack in low temperatures. That means they’re great for harsh environments. These coatings meet UL 94 V-0 for flame retardance.
    These coatings are thinner than potting compounds, so they flow into the smallest contours to cover your parts completely. They also don’t require a potting box or other container. Dispense these coatings with a gun (sold separately).

    Epoxy Potting Compounds for Harsh Environments

    Image of Product. Front orientation. Potting Compounds. Epoxy Potting Compounds for Harsh Environments.
    Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
    They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

    From shore to sea floor, these potting compounds are formulated for permanent submersion in water—even salt water. Use them to protect circuits and splices in pumps, underwater lighting, and other underwater electronics from corrosion and chemicals. Made of urethane, they withstand a wide range of temperatures, especially cold underwater conditions. They provide good electrical insulation and have excellent flexibility. Since they’re more flexible than epoxy compounds, they’re often used to protect against vibration and impact.
    Mix the two parts of these compounds together and pour them over components inside a potting box or other container. If mixing causes air bubbles, put the mixture in a vacuum chamber to remove them.
